Bad service Ford SA

Pathetic service. Bought a new Ford Ranger this year. When I switched off the radio, it wouldn't switch back on. Took it to Ford garage in Zeerust. Mechanic first said it was software problem. That didn't fix it. He disconnected the battery and reconnected it. Put in code, radio worked. I asked what the problem was, but he didn't know. Left radio on, few weeks later switch radio off, same problem. Take it to Allen Joss Montana, advisor says its a software problem. Ford knows about it, but nothing has been done to fix. Contact Ford SA, lady phones and asks if she could phone following day with answers. No phonecall. Contact Ford SA again 2 days later, say they will call. Nothing. Phone call centre, lady says ahe will escalate to a manager, but manager has 48hours to answer. What happened to initial 48 hours? They try to frustrate you into submission. Will never ever buy Ford again if that is how they treat their customers. To big for their boots
